They will probably not keep the speed if you guys keep abusing them with LinX(SP1)+AVX/prime at these voltages. Several people (including C-N and the author of the ud7 overclock guide) have gotten degrading overclocks after abusing the chips with repeated stress testing. After seeing this, I'm not going to run prime at high voltages anymore; it's just not worth risking the chip. I'd rather game for a day rather than burn my chip out running prime for 24 hours...
